Abstract: PURPOSE:To facilitate accurate positioning without using a complicated position controller by a method wherein a semiconductor chip holding part tapered toward its tip is loosely held and the outer circumference of the tapered part is pressed against the outer edge part of the recess of a package to which the semiconductor chip is die-bonded. CONSTITUTION:A collet 10 which fixes and holds a semiconductor device chip 20 is connected to a vacuum suction pipe 12 and the chip 20 is attracted and fixed to the chip fixing part 10a of the collet 10. The support arm 11 of the collet 10 is held by a manipulator linking part 13 elastically with a spring 13a or the like and can move the collet 10 to X-, Y- and Z-directions by a manipulator 14. The outer form of the collet 10 is approximately cylindrical and a tapered part 10d is formed so as to be tapered toward the chip fixing part 10a. The tapered part 10b is so formed as to have its outer circumference is pressed against the whole circumference of the outer edge part 21b of the recess 21a of a package 21 when the chip 20 reaches a predetermined position in the package. The collet 10 attracting and holding the chip 20 is positioned approximately above the position where the chip 20 is to be die-bonded and the chip 20 can be positioned easily by simply making the collet 10 descend.

Title: Glass substrate for photomask and formation of photomask
Inventor: TAMAOKI HIDEKAZU
IPC: G03F1/60
Filed: 1992-08-06
Abstract: PURPOSE:To reduce the size of a mask plotting device and to reduce the cost of production and to improve the contrast of plotted circuit patterns. CONSTITUTION:A glass article 13 is formed of a glass body part 11 and an ion exchange surface layer 12 and is irradiated with an electron beam from the surface layer 12 side, by which the surface layer 12 is blackened.

Abstract: PURPOSE:To prevent liquid from flowing out even if a container falls and permit liquid to be poured out without opening/closing a lid when the need arises by providing a valve device which opens an air path for taking air into a container only when the need arises. CONSTITUTION:A lid 3 of a viscous liquid container 1 is provided with a liquid outlet port 4 and a valve device 5. In the valve device 5, a valve 11 having a protrusion 19 is pressed and supported by a spring 14 in a valve chamber 13 formed by a cylindrical frame 12, and the valve device 5 is communicated with the outside of the container via a flow-in hole 16 formed on a ceiling 15 to serve as a valve seat 15 and with the inside of the container via an outlet hole 18 formed on a floor 17. An air path 10 formed here is opened and closed by the valve 11 at a position of the flow-in hole 16. In this container 1, an air path 10 normally remains closed so that air may not enter the container even if the container falls not to permit liquid to be flowed out. On the other hand, when the liquid is to be poured out, the air path 10 is opened by pushing the protrusion 19 to take air into the container so that the liquid can be poured out.
